Abstract
The invention discloses an ultrahigh-field-intensity intraoperative magnetic resonance scanning preparation device, and belongs to the technical field of medical apparatus manufacturing. The preparation device is composed of a coil, a frame, a base and rolling wheels, wherein the coil is of an annular structure which is consistent with a magnet hole in a magnetic resonance system which is 3.0T in field intensity; the frame is in the form of a gate; the coil is fixedly arranged in the frame by virtue of fixing clamps; the frame is arranged on the base; and the four rolling wheels are arranged at the bottom of the base. Since the coil is fixedly arranged on the frame and the coil is identical to the magnet hole diameter in height, an actual magnet hole diameter is simulated. Before using the magnetic resonance system which is 3.0T in field intensity, the base is pushed along a path which is set in accordance with a magnet moving route, so that an operation bed, an operated patient and a sterile covering dressing can run through the magnet hole diameter, and the height and angle of the operation bed are regulated, so that a purpose of completing scanning by moving a magnet once is achieved. According to the preparation device disclosed by the invention, unnecessary operation time and anesthesia time can be saved, the use safety of intraoperative magnetic resonance examination can be improved and medical risks of the patient can be reduced; and meanwhile, abrasion of related parts caused by magnet moving can be relieved and energy can be saved.
Description
Technical field
The invention belongs to manufacture technology field of medical appliance, relate to a kind of magnetic resonance imaging preparation device, especially can test the entrance magnet aperture smoothly such as surgical patient and operation sterile package dressing on operation table, operation table and carry out the copper coil of magnetic resonance imaging.
Background technology
At present, 3.0T superelevation field intensity intraoperative MRI system the most only Shanghai Huashan Hospital, No.1 Hospital of Jilin Univ., BJ Union Hospital, Zhengzhou University's attached First Hospital installation and operation, not yet there is similar relevant apparatus to report.When carrying out intraoperative MRI scanning, on operation table to be ensured, operation table, surgical patient and operation sterile package dressing simultaneously enter magnet aperture, and because underlying cause, need to take considerable time and attempt, operation table, patient and sterile package dressing just can be made to enter safely in magnet aperture:
1. this operation table is because high-intensity magnetic field reason, and for ensureing magnetic field evenness and operation safety during scanning, and the design of operation table need to reduce magnetisable material to greatest extent, and cannot the electronic equipment such as various sensors of design and installation, it is impossible to automatically reply scan position；
2. different due to surgical patient position, need repeatedly to adjust operation table height and angle repeatedly moving magnet trial, to ensure that corrective surgery position is positioned at magnet central area；
3. magnet is when 1 meter of scope of operation table, operation table needs power-off to ensure safety, and when there is height or angle difference, magnet need to remove operation table 1 meter of scope again, just can be once again powered up adjusting the height of operation table and angle, finally need to repeatedly test could enter magnet and be scanned.Greatly (about 15 tons), mobile slow, this process expends the long duration to magnet weight；
The most only move to intraoperative MRI with perusal person and cause difficulty, easily cause false judgment, damage magnetic resonance magnet, also may press into aseptic dressing and cause performing the operation various pipeline displacement or come off, threaten corrective surgery safety, even can directly extrude and hurt patient.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of superelevation field intensity intraoperative MRI scanning preparation device, it is possible to before moving magnet scans, convenient determination operation table could enter magnet aperture smoothly with surgical patient and is scanned.
The technical solution adopted for the present invention to solve the technical problems is to use coil, framework, base and roller to constitute superelevation field intensity intraoperative MRI scanning preparation device, coil is annular, consistent with magnet bore in the magnetic resonance system of 3.0T field intensity, framework is door shape, coil is fixed in framework by fixation clamp, framework is arranged on base, and four rolling is arranged at the bottom of base.Coil is fixed on framework, and makes coil height identical with magnet aperture height, simulates real magnet aperture.Before using the magnetic resonance system of 3.0T field intensity, move route set path according to magnet and promote base to make operation table, surgical patient and sterile package dressing extend there through, adjust operation table height and angle, reach moving magnet to complete the purpose of scanning.
Magnetic resonance system for 3.0T field intensity, the shape of its magnet bore is the circular hole that trapezoidal projection is arranged at bottom, in order to make coil coincide more accurately with magnet bore, the bottom of coil is machined with recess, recess is formed by a horizontal line and two skew back lines, and recess shape is identical with the trapezoidal convex shape bottom magnet bore.
Coil is also dependent on the shape customization in different magnetic resonance apertures, with other intraoperative MRI systems compatible.
The material of all parts is desirable that it is nonmagnetic, and coil is preferably with metallic copper material.
The invention has the beneficial effects as follows, non-essential operation and anesthesia duration can be saved, improve the safety that application intraoperative MRI checks, reduce patient medical risk, reduce magnet simultaneously and move the abrasion of the related components brought, save the energy.
This equipment can the magnetic resonance system of the highest support 3.0T field intensity, can be with the magnetic resonance system of backward compatible below 3.0T.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing is the schematic diagram of the present invention.
